Abstract: A log handling device, having a rotatable rotor provided with a log handler, and a feeder attached to the rotor for conducting an operating medium to the log handler. The feeder is arranged to wind around the rotor when the rotor is rotated in a first direction, and which feeder is arranged to unwind from around the rotor when the rotor is rotated in a second direction. The log handling device includes a rotatable second rotor to which the feeder is attached, and an operating device for rotating the second rotor synchronously with the rotor, such that the feeder is arranged to wind around the second rotor when the rotor is rotated in the second direction, and such that the feeder is arranged to unwind from around the second rotor when the rotor is rotated in the first direction.

Abstract: The embodiments relate to a system, devices, methods, and computer programs for determining a recipe for curable compositions. The system may receive information related to available sidestream based and/or virgin raw materials suitable for production of curable products. In addition, the system may receive a request to deliver a recipe for a curable end-product. The request may include target feature information of an end-product. The system may further determine the recipe for the requested end-product on basis of the received target information and the information related to the available raw materials. In addition, the system may provide separate user interface and/or communication interfaces for raw material producers and end-product manufacturers.

Abstract: Foundation, apparatus and method for stabilization of a foundation. The foundation comprises a subsoil and a pavement structure formed over it, which pavement structure includes a plurality of successive structural layers. At least one of these structural layers is a binder-stabilized structural layer which includes stone materialand a binder. Additionally, the stabilized structural layer is enclosed within a sleeve structure.

Abstract: A voltage source includes two electrically conductive terminals (101, 102) with an electrolyte (103) between them. Said electrolyte (103) is a mixture in which the main component is ash produced in a power plant or an incineration plant.

Abstract: A mixer and a mixing unit for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The mixer (6) comprises: a bucket part (27) for loading and transferring the side-stream material; a mixer apparatus (26) for mixing the side-stream material which has been loaded into the space delimited by the bucket part (27); a connecting device (25) for connecting the mixer (6) to a boom of a work machine (5); and at least one measuring device (S1, S2, S3) for determining properties of the material in the mixer (6).

Abstract: An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

Abstract: The invention relates to a video compression method to be employed in connection with the conditional replenishment transmission and receiving method. In the transmitter there are detected such areas of the image that are changed with respect to the previous image, and the picture information representing the occurred changes, along with the addresses of the respective picture areas, is sent into the transmission channel. In the receiver there is reconstructed the new image on the basis of the previous image and the picture information representing the occurred changes.
